问题：The ABAP program lines are wider than the internal table.
ALV自动转换成fieldcat，通过内表转换，如果代码长度超过72位，会系统Dump。
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
i_program_name = sy-repid
i_internal_tabname = 'LS_RECORD'
i_inclname = sy-repid
CHANGING
ct_fieldcat = gt_fieldcat[]
EXCEPTIONS
inconsistent_interface = 1
program_error = 2.
原因：函数K_KKB_FIELDCAT_MERGE，365行处转换问题
rssource-line长度设定72位，因此ABAP代码宽度不能超过72字符长度
